A couple more came to mind.
Little Charlie and the Nightcats, later Rick Estrin and the Nightcats
Rick Estrin, vocals and harp, always had been the frontman but made it official when Little Charlie, guitar, decided to get off the road. Rick's vocals may be an aquired taste so check out some samples on Amazon before buying. These guys are a great party band in the West Coast Blues style.
Check out Marcia Ball. She's not West Coast Blues but she knows how to get a party going. Her most recent, Roadside Attractions, is a great place to start. She plays in a New Orleans R&B style but draws from a lot of Blues and R&B styles.
John, it depends on which album you're talking about. Taj covers a lot of territory.
